Figure 4From: Clonal expansion is a characteristic feature of the B-cell repertoire of patients with rheumatoid arthritisAnalyses of B cells from paired samples of blood (B) and synovialtissue from both the right (R) and left (L) hips of the same rheumatoidarthritis patient. Results using both the genomic DNA-based assay and thecomplementary (c)DNA-based assay for the three major immunoglobulin isotypes(M, G, and A) are shown.
